This invention relates particularly to an improved work table intended especially for use by persons engaged inmending pneumatic tires, either the casings or the inner tubes of such tires. 7 I

The object of the invention is to produce such a work table in compact and convenient form embodying means for facilitating the various steps or operations concernedwith.

stem, B, below said head.

the mending of such tires.

In the accompanying drawings, Fig. 1 is an elevation or" a structure embodying my improvement; 7 I Fig. 2 is an elevation of he structure looking at Fig. 1 from the right;

Fig. 3 is a horizontal section on .the line, 33', of Flg. 2;

Fig. tis an upright section ontheline, 44, of Fig. 1, looking toward the right;

Fig. 5 isa horizontal section on the line,

55, of Fig. 2;

Fig. 6 is a section on the line, 66, of Fig. 2,1ooking upward;

Fig. 7 is a horizontal 77, of Fig. 4. V

Referring to the drawings, Ais a base adapted to rest on and be secured to afioor. A is a tubular column rising from said base and open at its upper end and having section on the line,

in'the upper edge of its wall tour notches,

A lower stem, B, is telescoped slidably and ing is accomplished by means of afoot lever,

A fulcrumed at A to the column, A An upright lifting rod, A has its lower end coupled to the rear end of the lever, That rod extends slidably through a sleeve, Afion a bra'cket, A fixed on the column, A. The upper end of said rodis bent laterally and formed into a horizontal arm, A extending aroundor partially around the'stem, B, close to the lower part ofthe head,'B of the stem, B. By depressing the free end of the foot lever, the lifting rod, A is pushed upward, whereby the arm,.A is made to lift the head, B and the stem, B,

whereby thetable and parts supported.

by the table and also the upper stem, D, are lifted. 'Then the table top, Q, be engaged by the hand of the operator for turning the table top and parts associated therewith;

The upper stem, D, e'Xtend s downward through the bushing, C and is threaded through the head,B-, and extends-into the By turning the stem, D, its height in the stem,'B, and relative to the table top, C,wmay be varied. Above the table a hand wheel, D ,-sur. rounds and is keyed to-the stem, D.- Said wheel is to be grasped by the hands of the operator for turning, said stem. Immediately above the husl1ing,.C the-upper stem, D, is surrounded by a .i am nut, D", on which is a hand wheel, D. l/Vhenthe stem,-D, has been turned to bring it to the desired height,

the handwheel, D ,.isto be turned int-he proper direction to drive the jam nut, D down against the bushing, 0 forjamming the threads on the stem, D. The hand wheel, D has its hub directed upward. Above said 'hub and resting thereon, a circular tool tray, D looselysurrounds the upper st-em, D, and is rotatable on said stem.

while resting on said hub.

Infltheupper end of the upper stem, D,

is an upright socket, D onthe axial line of saidxstem and opening upward- A metal arm, D, has on one end a, finger, D resting rotatably in said socket forthe support of said arm. The other end of said, arm is in the form of a hook, D which isf'approXima-tely in a; line rising from theiedge of the I table top. In the. form shown bythe drawings, the table top,-.G,.is made otwooden boards hav ing their, edges fitted or glued together. 5011* the under facegofthe top are two transverse reinforcing strips of'wood, C suitablysecured-to'the top, as by means of screwsor nails; A pair or parallel. tire supports, C

are applied slida-bly to thelowerface of the top.v These are in the form. of metal rods slidable in one-of the binding strips, B?, and in one of the guide strips, 0", secured to the lower face of thetop. The'two supports, Came shown joined by a transverse jun ber, C ,;to move far enoughoutward and Y edge when, said members arenot being used.

The outer or free ends of the members, C

are turned up slightly or to any desired extent for the purpose of holding the tire, as will be described further on. r

At the edge of the table top opposite the edge from which the members, project,

a pair of brackets, E, are secured to the lower face of the top, C, and made to pro ect outward a short distance beyond the ec ge of the top. On each of said brackets is supported a standard, E Between the upper ends of said standards'is a form, E each end of the form being attached to the end of the adjacent standard. Said formis approximately the shape of a segment of a pneumatic tire casing, the 'form'being in an upright plane and the axis of the circle in which the form lies being below the form;

On the under face of the table top is a plate, F, applied fiatwise to the top and pivoted thereto at F to turn in a horizontal plane. This plate may be folded under the table top or extended outward perpendicularly to the adjacent edge of said top. A guide member, F engages .the plate when the latter is in the outer position, the guide member and the hinge member together supporting the plate. Said plate is to be used tor'supporting the inner tube of the pneumatic tire while said tube is being mended.

This work table is adapted to the several operations already mentioned. ing on'the inner part of a pneumatic tire casing, said casing is hung on the arm, D while the lower part of the casing rests on the pair of supports, C. The finger, D, is rotatable in the socket, D of the upper stem, D. This allows turning the arm, D [to the working position after the stem, D,

has been turned tov vary its height to change the elevation of said arm as may be necessary for tire casings'of different sizes.

When the exterior of the casing is to be mended, the casing is to be hung on the form E the form being placed inside the casing. By rotating the table, the operator Vina-y, without 'changingfposition,bring said, form, E or the pair of supports, 0 ,01 the plate, F, to the operator. Furthermore, if the operator desires to change position to have better light on his work,'he can make that change and'then turn the table top to bring the desired working part or parts before him. The inter-en a 'ement"between the tubular column, A and thelower stem, B, is to be of sufficient strength to prevent turning of the table top when such turning is not desired The tool tray, D4, is conveniently located for holding all the tools ordinarily needed For work- ,eee,553
